He's been surprising consistent for the Wiz this year averaging career highs in scoring, FG% and 3pt %.

In February alone:
13.1 ppg
52.6 FG%
56.6 3pt%

Isn't he leading the league in 4 point plays too (slightly arbitrary, but seems to have a knack for getting fouled).

The reason guys like Webster and Beal play so well with Wall is because of how disciplined they are. Last season, Wall led the league assists from the corner three and he's really excellent at drawing defenders from the wing and then finding the man in the corner. And this was playing with guys like Crawford and Young who liked to freelance a lot. Playing with Webster and Beal is so much different as both them know when to shoot to the corner when Wall is driving. Also, watch when the Wall is flying down the court on a fast break, neither of them fill the lane like you're traditionally taught to, instead they immediately sprint to the corner and let one of the bigs trail Wall. If there's enough resistance going to the basket, Wall almost always finds one of the wings in the corner for an open three.
